Abstract (en)
Provided is a spunbond nonwoven fabric that is easy to produce due to excellent spinnability and has uniform and sufficient quality including mechanical properties while the spunbond nonwoven fabric is highly filled with an inorganic substance powder. An inorganic substance powder-blended spunbond nonwoven fabric is composed of a fiber, the fiber including: a thermoplastic resin and an inorganic substance powder in a mass ratio of 50:50 to 10:90, and an ethylene-based polymer wax having a weight average molecular weight of 400 or more and 5,000 or less in an amount of 0.1 part by mass or more and 3.0 parts by mass or less relative to 100 parts by mass of a total amount of the thermoplastic resin and the inorganic substance powder.
